Yoga 2 Pro - Auto brightness feature and how to disable in Windows 8.1
I have a Yoga 2 Pro system and the brightness on my screen is constantly adjusting. This is most obvious when making the move from the desktop to Metro. After hitting the windows key, I can see the brightness increasing in stages (about 4 times) after flipping over to Metro.
I have disabled Auto-Brightness under the Change My PC Setting -> Power and Sleep menu. I have also disabled Enable Adpative Brightness under Windows Power Mangement but the issue still persists.
Is there any other location I might be missing a setting that can be affecting this ? Brightness is set to full and keeps dipping down.
There are a few factors if your screen appears dim, or the brightness changes automatically and frequently.
You can check the three methods below to ensure the auto brightness adjustment feature is not enabled.
1) Brightness adjustment via Power and Sleep in Windows 8.1
You may wish to disable the Automatic Brightness setting in Windows 8.1. This setting is enabled by default; however, some users may not wish to make use of this option.
To disable Automatic Brightness:
First, begin by swiping the right edge of the screen or touchpad to fly out the Charms bar
Next, tap 'Settings'
Now, in the bottom right corner, tap “Change PC Settings”
In PC Settings, tap "PC and devices"
Under "PC and devices", tap "Power and Sleep". The Brightness setting allows you to toggle the automatic brightness feature on and off. Simply drag the slide controll to the left to turn off.
2) Check your Intel graphic card properties
If you find that your screen continues to automatically adjust brightness, please try the following:
Right click on the desktop and select "intel graphics properties."
Now, select the "on battery" tab and turn off "Display Power Saving Technology."
